Would I be able to take my Verizon phone and switch to T-Mobile? Or is that...

...not possible? So, I am done with Verizon. But my phone is cool and T-Mobile doesn't have it. Is there a way that I can switch services without switching my phone (plus, I don't want to sign another contract)?

I think you will need to sign another contract (to get phone service from T-Mobile) but I am quite sure you can still us eyour phone. Call customer support and ask them?
